Solar Photovoltaic Energy

Kimberly Said: What do you think of photovoltaic and solar energy field as a field to study? We Answered: I think that energy technology will be one of the really good engineering fields for the next few decades. Concerning the narrowness of it, all areas where you get a master’s degree narrow focus but increase…

Application of 80 Watt Solar Panels in India

Photons, light particles from the sun, are converted into an electron stream in the familiar blue solar panels with silicon solar cells. In a pilot project that will take a total of seven years to complete, they will test the benefits of this step towards self-sufficiency in energy supply on…

Solar Panel Efficiency

Darryl Said: Solar Panel Efficiency? We Answered: I’ve operated a 25 kilowatt (kw) solar panel system for two years (144 panels, rated at 190 watts each, just about like yours). It averages 110 kilowatt hours (kwh) per day, but clear days get about 160 kwh. My system generates about 3300 kwh per month (we…

Electric Energy Solar

Roberto Said: Does anyone know if it is possible to power an electric fireplace & blower with only solar energy? We Answered: Yes, it is possible even if it has heating elements. It sounds as if the Electric Fireplace has an electric heating element and a blower fan. The higher the kilowatt rating of…

Photos Of Solar Energy

Ellen Said: What is the Energy required to conduct electrolysis?? Is Solar Energy Sufficient? We Answered: Depends on what rate of electrolysis you desire. Almost any voltage would be sufficient. Adding salt to water lowers the resistance levels also to make the effects a little more dramatic. Hope this helps. Kathryn Said: How do we…
